SUPPORT FOR THE ROLLERS OF SPINNING-FRAMES, 80C.

SPECIFICATION forming part of Letters Patent No. 408,275, dated August 6, 1889. Application filed April 17, 1889- Serial No. 307,596. (No model.)

To all whom it 'nmy concern:

Be it known that I, EDMUND TWEEDALE, a subject of Her Majesty the Queen of Great Britain, residing at Accrington, in the county of Lancaster, England, have invented a certain new and useful Improvement in Supports for the Rollers of Spinning and other Frames, of which the following is a specification.

My invention relates to an improvement in the supports or mountings of the top rollers of roving, spinning, and twisting frames, the object being to secure and preserve a correct alignment of said rollers, so as to prevent the twisting of the same According to my invention, I employ an improved form or section of finger, which carries the nebs or bearing-blocks of the top rollers, upon which said blocks may be adjusted and secured without being twisted in the act of screwing them down, while, to prevent the nebs or blocks themselves falling and bearing upon the drawing-rollers below, and to allow for their lateral adjustment, I provide suitable means for securing the brackets carrying the fingers upon the bracket-shaft.

Referring to the accompanying drawings, Figure 1 shows in elevation a portion of a roving, spinning, or twisting frame with. the top rolls mounted according to my invention. Fig. 2 is a left-hand end elevation of the same. Fig. 3 is a side view of the bracket-shaft, bracket, finger, and nebs upon an enlarged scale. Fig. 4c is an end view of the same, and Fig. 5 is an end view of one of the nebs detached.

The finger at, I form five-sided in crosssection, as shown, and arrange it in the bracket 1), so that one of the flat sides is on top and thus presents a surface for the screw 0, which secures it in the same. The lower portion of the hole in the bracket is formed of a V shape, so that two sides of the finger may rest therein, as shown. The holes through the nebs or bearing-blocks cl are similarly formed of a V shape be low. Holes of this shape maybe formed by first boring them out round and then slotting or filing the two flat faces therein. It

will be evident that a three-sided or other angular figure in cross-section will be equally good for the finger, all that is wanted being flat faces or an angular bearing face for the V-shaped part of the holes in the nebs and brackets, and a flat face for the screws 0 in the brackets and the screws 6 of the nebs. In this way the nebs may be set in position to receive the top rollers 7c, and. the screws tightened up without fear of twisting them or forcing them out of line with the opposite one, which receives the other end of the roller, the journals of which, it will be seen, are simply dropped into the groove in each block, so that the top roller rests upon the drawing-roller below.

To prevent the brackets b twisting on their shaft f and possibly allowing the mobs to fall into contact with the drawing-rollers g, I form grooves 71 transversely across the top face of the shaft, as shown in Fig. l, and key the bracket into the same by means of a taper key 1', thus holding the bracket and preventingit from turning, while the recesses h at the same time allow of the brackets being shifted laterally along the shaft and keyed in the same when the top rollers happen to be varied or differ in length.

VVhat- I claim, and desire to secure by Let ters Patent, is

1. The combination, with an angular-faced finger and bearing-blocks having holes with angulanbearing sides therein, means for securing the same to said finger, the grooved shaft, the bracket having a hole adapted to receive the angular finger, means for securin g the finger in the bracket, and means for securing the bracket to the shaft, consisting of the pin fitting in the groove of the shaft, substantially as described.

2. In combination, the lJGtl'll'lQ-l)l00lCS, the finger for supporting the same, the bracket for holding the finger, a shaftv for supporting the bracket, said shaft being grooved transversely, and the pin inserted in the groove and between the bearing-block and shaft, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
